Extra code getting appeneded in custom taxononmy name field

Hello,

I created a custom taxonomy viz Email and entered a email address. But when I came back to modify the slug, I saw the following code appended in the Name field of the Email taxonomy but slug remains the same.

some-email-address@test.com/* <![CDATA[ */(function(){try{var s,a,i,j,r,c,l,b=document.getElementsByTagName("script");l=b[b.length-1].previousSibling;a=l.getAttribute('data-cfemail');if(a){s='';r=parseInt(a.substr(0,2),16);for(j=2;a.length-j;j+=2){c=parseInt(a.substr(j,2),16)^r;s+=String.fromCharCode(c);}s=document.createTextNode(s);l.parentNode.replaceChild(s,l);}}catch(e){}})();/* ]]> */

Any clues what could be wrong and from where this code is getting appended.

Thanks,

Alok
